Odaily Planet Daily News Optimism announced that its open source, permissionless proof-of-stake has been launched on the OP Mainnet, and the OP Stack has reached the first stage of decentralization. Soon, more OP Stack Chains will be upgraded to include this feature, with the initial projects being Base, Metal, Mode, and Zora. The fault proof allows the extraction of ETH and ERC-20 tokens from the OP Mainnet without the need for a trusted third party, enabling users to challenge and remove invalid withdrawals, contributing to the security of Superchain. In the coming months, the official will launch more proof systems on the testnet, including Asterisc and Kona. Proving the reliability and robustness of these redundant proof schemes will help the superchain achieve the decentralization of the second stage, managed solely through smart contracts.

PANews June 11th news, according to The Block, OP Labs has launched the fault-proofing on the L2 blockchain OP Mainnet. The fault-proofing system allows for the extraction of Ethereum and ERC-20 tokens from OP Mainnet without the need for a trusted third party. Fault-proofing is a mechanism of the Ethereum L2 network that allows users to defend against potential fraud or incorrect transactions. Previously, OP Mainnet did not have fault-proofing, which required users to trust the operator to submit accurate state roots to the mainnet. In the future, fault-proofing will be extended to other L2s built on OP Stack, including Base, Metal, Mode, and Zora.

Metal L2 will undergo a smart contract upgrade on June 24th to ensure a smooth transition for wallets holding Metal DAO (MTL) tokens. The snapshot date is June 24th, and the airdrop date is June 26th. If you use a supported non-custodial wallet, you can switch networks after the airdrop to see your MTL balance on the Metal L2 mainnet. MTL v1 tokens will be converted to MTL v2 tokens at a 1:1 ratio. Wallets supported by Metal L2 include WebAuth and MetaMask.
